Copper Smelting Process

The copper oxide minimum minerals are dissolved by the acid to give a blue copper rich solution mainly of copper sulfate. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. This process as the advantage of avoiding the smelting and refining ...

Copper Smelting Industry Description and Practices Copper can be produced either pyrometallur-gically or hydrometallurgically. The hydromet- allurgical route is used only for a very limited amount of the world's copper production and is normally only considered in connection with in-situ leaching of copper ores; from an environmen-tal point of view, this is a questionable produc-tion route ...

Copper flash smelting is a relatively new process which has been in operation since the 70's and is a pyrometallurgical process used in conjunction with copper sulphide concentrates. The main key facilitators produced by the process include controlled oxidation of Fe and S, a large evolution of heat and the effective melting of solids.

While particle combustion and chalcopyrite oxidation in suspension smelting is well understood, few studies are available regarding the melt-melt reactions and the separation between copper matte and slag in matte smelting. In the present work, experimental investigations in air and argon atmosphere were conducted using a mixture of synthetic slag and chalcopyrite concentrate. The sequential ...

Copper Smelting Process

Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed.

31.01.2018 · So far, few studies have addressed the size changes experienced by copper concentrate particles during oxidation under flash smelting conditions. The first documented work on this subject was due to Jorgensen who measured the size distribution of chalcopyrite concentrate particles in a laboratory reactor by an image analysis technique.

The final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels. This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining.
